During subsea pipeline pre-commissioning or other subsea pumping operations into wells or pipelines, a remotely operated vehicle (ROV) is often utilized to provide power to locally deployed pumps. For example, high pressure and lower pressure pumps may be deployed on a skid for subsea pumping or hydrotesting of a pipeline. The skid may be carried by an ROV or deployed on the ocean floor adjacent a pipeline. The ROV is utilized to connect the pumps of the skid to the pipeline or an appropriate manifold. Thereafter, power from the ROV is utilized to operate the pumps. However, the operations are limited by the available power from the ROV. In many cases, the lack of power means the pumps cannot achieve the desired pump flowrates for a particular operation. For example, lower pump flowrates may limit flooding pig speed through the pipeline, chemical injection rates or the rate of pressurization.
